Ets o2 eliminator downpipe dump/recirculate?
Ok so I finally decided on the ets v2 exhaust, and testpipe. I'm just a little confused on the downpipe by them. What is the o2 eliminator, because it is expensive. Also, it gives me an option of dumping to the atmosphere our recirculating. Is one better then the other? I wanna try and keep the whole system ets. I don't wanna mix and match. I don't know much as I am new to the modding scene but many of you have been helpful before, so any insight on this would be greatly appreciated. Thanks

To the best of my knowledge, the O2 eliminator means the downpipe would replace the stock downpipe and the stock 02 housing (the bellmouth shaped part that bolts to the exhaust housing of the turbo). Both ETS downpipes are divorced so the exhaust gas from the wastegate would go through a seperate system than the normal exhaust flow, if its recirculated they come back together, if its open dump then the wastegate flow is dumped straight to the atmosphere.
In terms of which is better I am not sure for power purposes, but I have a feeling that an open dump dp is extremely loud under WOT and most likely won't pass emissions testing (if thats an issue).

Ountz is correct. The dump to atmosphere version will be loud under WOT. The reason it's more expensive then other downpipes is we include an integrated o2 housin, not just a straight piece of pipe.
The reason we run a divorced downpipe is to separate the exhaust gases from the wastes gases to prevent unwanted turbulence. This allows the exhaust to flow smoothly and have the wastegate gases either vent to atmosphere or recirculate around 13 inches back into stream.
We have found an open o2 housing to interrupt exhaust flow when the wastegate opens and closes.
If you have any questions, let me know!
Thanks,

Which is better as far as gains? Also, is it true the dump version will not pass emissions. I know I'll fail with the testpipe pipe but when it comes time for that I was gonna put the stock cat on. Because that would be much easier then messing with the downpipe again right? Thanks
Thanks!

I can personally vouch that the ETS open dump downpipe is:
A) Loud as f**k under WOT
B) Sounds like a mean stock car when you're on it and is known to cause chickens to jump up and have heartattacks
C) Was the last piece to completely flow my engine the RIGHT way with zero restrictions, reducing all exhaust turbulence
I absolutely LOVE the exhaust, the construction of it, and the way it sounds. It surprises everyone, and feels so smooth.
Mine has been in since end of October and no cracks. Superior craftsmanship. I was wow'ed by the quality when I had it in my hands.
Side note: Any sort of O2 dumping DP is never recommended for the street unless you like the noise, as I do. But you will definitely notice a difference in the way the car rolls up through the rpm's smoother.

Lol I like loud too but just didn't know if I could live with it. I went with the recirculated, hope I made the right choice. I want some noise but nothing to extreme where the cops will be on me all the time.

Hmm this got me thinking...
Im about to order the ETS dump downpipe and the catted HFC midpipe, but would that even make any sense since the dump is just going to by pass the midpipe.
My logic is that under normal driving (below 3000pm), the exhaust would still flow through the HFC and take out most of the smelly hydrocarbons?
